WHEEL-HUB.

SPECIFICATION forming part of Letters Patent No. 686,160, dated November5, 1901.

I Application filed October 30, I900. $erial No. 34,929. (No model.)

To all whom it ntcty concern:

Be it known that we, FREDERICK STACY, HORACE E. MURPHY, and CARL B.HUDsoN, residents of Wabash, in the county of Wabash and State ofIndiana, have invented certain new and useful Improvement-s in Wheel-Hubs; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

The invention relates to vehicle-wheels, and has for its object toprovide metal or composite hubs for wheels such that each wheel will runtrue and in which the spokes and box can be readily replaced when brokenor worn. A suitably-true bore cannot be produced with reasonablecertainty in cast-iron or composite hubs, because of the inevitablevariations in their casting. Wheels with wooden hubs have been held inframes and the hubs bored to receive the boxes for the wheel-spindle. Wehave devised a method whereby a like result can be secured in hubscomposed mainly of cast-iron. 1

Theinvention consists in the means for providing a true bore incomposite wheel-hubs consisting mainly of metal.

In the accompanying drawings, Figure 1 is a longitudinal section of theimproved hub. Fig. 2 is a transverse section. Fig. 3 is a perspective ofa collar on the screw-threaded end of the hub, the latter being brokenaway.

Numeral 1 denotes a metal hub having a lining 2 of Wood and an axle-box3. The hub 1 has a circumferential flange 4, which coacts with a flange5 on a sleeve 6, that slides on the hub. ferential groove 7, whereby itis adapted to be slid over a corresponding circumferential projection onthe hub when the sleeve is forced by a collar 8, screwing on thethreaded end of the hub 1, against spokes placed between the fianges 5and 7. The collar 8 covers the end ofthe box 3 and holds it in place. Toremove the'box for the substitution of another, it is only necessary toremove the screwcollar 8 and drive out the box. The collar beingremoved, the spokes may one or more be removed and others substituted,or they The sleeve has a circummay be tightened longitudinally, ifnecessary, by driving wedges under their ends next the hub, and theseoperations can be performed by unskilled labor. The flanges inclose thespoke-sockets laterally, the bottom of said sockets and the hub-flangebeing cast integral with the hub. The wooden lining is tubular Withoutside openings and fits the bore spoke-sockets after they are driven, andif formed before they are driven it is diificult to secure properregistry with tho spoke-sockets in the metal part of the hub. Further,the lining is weakened by the shoulder and sockets, and for this reasonis liable to be split or broken.

It has been found impracticable in wheels having composite hubs of thecharacter above noted to insure that the wheel shall run true. Thisdifficulty results from unavoidable variations in the casting and thedifiiculty of inserting the tubular wooden linings so that they shall beand remain true with respect to the plane of rotation of the wheel. Bythe present method a metal hub receives a solid wooden core, driven intoand thereby compressed therein. The other parts of the wheel, except thespindle-box, are then assembled. In this operation the rim is tightenedon the spokes, and the latter are firmly bound in and upon the metalhub. Each Wheel thus far constructed is centered and the wooden corebored to provide for the insertion of the box in its proper relation tothe 5 plane of rotation. By this means each Wheel having a metal hub ismade to run true on its spindle notwithstanding variations in cast ingthe hub.

We do not claim hubs composed of metal and Wood nor the boring of woodenhubs. Our improvement is characterized by a wooden core of a metal hubbored out in proper relation to the plane of rotation of the Wheel, suchcore having been driven tightly into and thereby compressed in the huband adapted when so bored to receive the spindle-box.

We are aware that wooden hubs have been bored and that cast hubs havebeen provided with wooden linings. Our improvement provides forinserting in a metal hub a solid core which is subsequentlybored toproperly center the wheel and then provided with a spindle-box, and itis characterized by constructions particularly hereinafter pointed out.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-
